Plural Publishing, San Diego, has released Digital Hearing Aids by James M. Kates, EE, a 464-page volume providing an overview of the signal-processing strategies implemented in modern digital hearing aids.

Algorithms ranging from dynamic-range compression and directional microphones to sound classification and binaural noise suppression are explained.

The basic equations describing the signal-processing algorithms are presented, along with full explanations for readers who are less comfortable with the mathematics, and each processing strategy is accompanied by a summary of its effectiveness.

The text is intended for a graduate audiology course in hearing aids and hearing-aid technology.
